It is unfortunate that you cannot "browse" already written guides. Perhaps the author of a guide can choose if he wants it to be publicly visible which will show it in the browse-list, publicly accessable which won't show it in the browse-list but anyone who knows the link can view it OR private which will be like the publicly accessable except it will require a password that the author can set himself and give to anyone he wants to be able to access the guide via the link.

It could even let users log in and be able to have an account and "publish" guides so people can view all guides by a specific person.
Man this has a lot of potential! Right now though, it's a great tool but not very.. inviting.
